Steps:

1. Do your research. There are numerous types of bindings to choose from. Decide whether you'll need a racing binding or an all-around binding.

2. Make sure the bindings are torsionally rigid. This means that the binding ought to twist sideways a bit when you exert pressure on the side, but should return to its original position when you ease up on the pressure. 

3. Check to see that the tension gauges are functioning properly. Adjust the tension of the back and front of the binding by tightening or loosening the screw connected to each gauge. The higher the tension gauge is set, the more force it takes for the binding to release the boot.

4. Inspect that the safety brakes are fastened to the binding properly. 

5. Determine that the back binding's moving parts move properly. The heel plate should click down to engage the boot. This pressure pulls the safety brakes up. Most bindings slide forward and backward slightly for fine-tuning.

6.Try out demo bindings on the slope if possible. 

7. Ask questions of the salesperson. Different bindings have different technical benefits that are often difficult to assess from a visual inspection.
